IMPROVEMENT IN SHUTTLE-MOTIONS FOR LOOMS.

Specification forming part of Letters Patent N 0. 213,183, dated March11, 1879; application filed September 24, 1878.

To all whom it may concern:

Be it known that I, ALFRED FAULKNER, of Jersey City, in the county ofHudson and State of New Jersey, have invented a new and usefulImprovementin Shuttle-Motions forLooms; and I do hereby declare that thefollowingis a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

This invention more particularly relates to shuttle-motions fornarrow-ware looms, but is also applicable to the shuttle-motions ofother looms in which the shuttle is carried or driven by a carrier ordriver having a positive rectilinear motion.

The improvements consist, first, in certain means whereby a leverconnected with the shuttle carrier or driver, for imparting to the sameits necessary motion back and forth, is caused, at its connection withthe said carrier or driver, to move in a right line; also, in certainmeans whereby the said lever and the shuttle carrier or driver arecaused to move more rapidly at and near the middle of the stroke than atthe commencement and termination thereof, all substantially ashereinafter described, and pointed out in the appended claims.

Figure 1 in the accompanying drawings is an inverted plan view of ashuttle-motion constructed according to my invention. Fig.2 is avertical section of the same at rightangles to the line of motion of theshuttle. Fig. 3 is an inverted plan view of the before-mentioned leverand its immediate appurtenances.

A is the shuttle carrier or driver, represented as furnished withrollers a a, running upon a straight guide-rail, B, on the loom-framing.This shuttle carrier or driver may be of any known or suitableconstruction.

0 is the lever for giving the said carrier or driver its motion back andforth. This lever is represented as being moved horizontally by means ofa rod, D, which connects it with a lever, E, actuated by a cam, F, onthe shaft G of the loom. The said lever is connected at its front endwith the carrier or driver A by means of a pin, 1) but instead of havinga fixed fulcrum at its rear end its rear portion is fitted to slidelongitudinallyback and forth through an oscillating fulcrum-yoke, H,which is pivoted bya fulcrum-pin ,0, into a hanger, I, which is securedto the loom-framing, the said yoke being free to oscillate with thelever on the fulcrum-pin c as motion is imparted to the lever.

The movement of the carrier or driver being confined to a straight lineby the straight guide the fulcrum-pin c, the rear portion of the leverhas to move longitudinally through the yoke H. In order to render this.movement easy, anti-friction rollers cl d are fitted to the yoke 5 butthese rollers might be dispensed with.

The rod D is connected with the lever G by means of a pivot or pin, 6,which is secured in a slide, J, which is fitted to slide lengthwise ofthe lever G in a slot, f, provided in the said lever and the same pivotor pin 0 connects the said rod and slide with a crank, K, which ispivoted by a pin,g, to the loom-framing. This crank K does not assist intransmitting motion to the shuttle driver or carrier, but controls orregulates the motion thereof in the following manner: The pivot or pin0, which connects the lever O with the rod D, being compelled by thesaid crank to move in the arc of a circle, (shown in dotted outline inFigs. 1 and 3,) has the effect of varying the velocity of the motion ofthe lever O and of the shuttle driver or carrier in such manner thatsaid velocity becomes less in the earlier and later portions of thestroke of the latter when the position of the crank is at a greaterangle to the lever O, and becomes greater when the position of the saidcrank ap; proximates to a position in line with the said lever. By thismeans there is less resistance in the starting of the shuttle, and themomentum of the shuttle and shuttle-driver is more easily arrested atthe termination of its stroke than if the rod D were directly connectedwith the lever, and the shuttle is caused to move faster while in thewarp. Moreover, by the action of the crank the slide f and rod D arecaused, when the shuttle-carrier has arrived at either end of itsstroke, to be farther from the fulcrum of the lever O and nearer to theshuttle carrier or driver, so as the better to brace the lever in suchposition.

I claim-- 1. The combination, with the reciprocating shuttle driver orcarrier A, of the vibrating and longitudinally-moving lever C, extendinglaterally from said driver or carrier, the rod 1), cam F, lever E,having aprojecting pin engaging with the groove of said cam, and theoscillating fulcrumyoke H, substantially as described.

2. The combination, with the shuttle driver or carrier, of the vibratingand longitudinallyengaging with the groove of said can], sub-'stantiallyas described.

3. The combination, with the shuttle driver or carrier, of the levenG,rod D, cam 'F, lever E, pivot e, slide J, crank K, and oscillatingfulcrum-yoke H, substantial]; as and for the purpose herein described.
